As for Nero Info Tool - this can be downloaded separately and does not require installation. ftp://ftp6.nero.com/tools/InfoTool.zip - just unzip and run the application.
Not necessary if you have ImgBurn installed - there is also a “drive capabilities” option integrated.
The inability to handle DVD-RAM (assuming that the drive supports these) could be either some kind of software problem, or the drive starts getting faulty.
OK thanks, I downloaded the info tool and it reports the drive as reading and writing to DVD-RAM . Under disk details it said on most disks I put in that there was no disk in drive. It did however manage to read one mini RAM disk from my Video Camera. But then when I tried to play that file in VLC it froze up. One might start assuming from the above that the drive is on its way out BUT, all DVD-R and RW disks and CD all read fine. So surely if it was hardware then it would have trouble with all disks and NOT just RAM disks.
